摘要： Fluid level in a container is determined using a single pressure transducer connected to a portable body. The body contains a computer having a memory in which fluid level-to-fluid volume conversion data are stored for different shapes of containers so that fluid volume can be readily obtained for the shape of the respective container once fluid level is determined. These features allow a single monitoring apparatus to be used for monitoring different types of containers. The apparatus preferably includes a radio so that multiple apparatus can communicate in a system with a central remote operator interface device. Fluid level is determined by dividing a pressure reading from the bottom of the fluid by a fluid density determined from two prior pressure reading taken across a known distance (density equals the difference between the two readings divided by the distance).

摘要： A portable apparatus for controlling the production of a mixture of a fluid and a plurality of additives utilizes a unified control panel having all of the necessary controls compactly contained in a single housing for providing both automatic and manual control of each of the additive channels through which the additives are mixed with the primary fluid. The control of each additive channel is achieved through a software controlled algorithm by which errors are only incrementally, rather than totally, applied to prior drive signals at any one time.

摘要： An apparatus for monitoring a plurality of operations, particularly on an offshore drilling rig, comprises a portable housing, a plurality of dedicated monitoring units associated with the housing, and a master microcomputer unit associated with the housing for handling information transfers between each of the dedicated monitoring units. Each monitoring unit includes a dedicated central processing unit which controls the operation of that unit. Control is maintained over a number of transducers which detect various physical conditions associated with the monitored operation. The electrical signals obtained from monitoring the conditions are processed and displayed on respective display consoles located in the housing. Intercommunication among the various units is achieved through serial input/output devices establishing communication channels between each unit and the master microcomputer unit.
